Amiga Warpengine 68060-68040 adapter

AMIGA WARPENGINE 68060-68040 ADAPTER

The adapter allows you to run a 68060 on a card only intended for the 68040. The cards concerned are therefore:

·                     the Commodore A3640,

·                     the WarpEngine from MacroSystem US,

·                     the G-Force 040 Combo from GVP, 

·                     the Phase5 CyberStorm MK1 040,

·                     the Apollo 1240 with Mach130 from ACT,

·                     the 040-500 from Progressive Peripherals and Software,

·                     the RCS Management Forty Merger. 

·                     Others?

How to Build

The upper  PCB - 68060

Building the 68060 socket is definitely the most challenging part because it needs to be made out of pin strip headers. To make next build easier, I created a diagram for building the 68060 socket using the 30-Pin Strips while leaving little waste. 

This configuration needs a total of eight 30-Pin strips, build the 68060 header, and leave 20 pins for the two 10 pin strips needed off to the side of each socket on each PCB.

This diagram is looking at the top of the 68060 PCB. The yellow and red pins need to be soldered but should be trimmed so they don't connect to the 68040 socket. 

The following information shows the number of pins in each lettered segment on the diagram. The strips are numbered 1 - 8.

The lower PCB - 68040

How to connect the bottom layer with the top layer here you can find the connection schema of the layer. The coloured pin should not be connected .

Note:

There was a small problem in the exec.library of Kickstart 3.0 and 3.1: Commodore did not support the 060, they stopped at 68040. The trick found by the third party manufacturers of the 68060 card was to add a few lines of code to deactivate the Fpu of the 060 at startup, so that the Amiga can finally boot with complete peace of mind... Activation of the Fpu was then done later...

All 060 accelerators available on the market had these few lines of code in an eprom present on the board. Some manufacturers also added, for example, Scsi drivers...

In short, you really need to deactivate the Fpu at startup with a 68060 and Kickstart 3.0, 3.1 and even 3.9!
